IMPROVEMENT IN RESERVOIR COGKING-STQVES.

p Specification forming part of Letters Patent No. 162,@57, dated May 4,1875; application filed February 13, 1875.

To all whom 'it may concern:

Be it known that I, GEORGE H. PHILLIPs, of Troy, Rensselaer county, NewYork, have invented Improvements in Water-Reservoir Stoves, of which thef'ollowing is a specification:

The object of my invention is a water-reservoir stove, in which theproducts of combstion from the fire-place, whether caused to circulatearound the oven or to pass directly to the chimney, are always broughtin contact with the water-reservoir; and this object I accomplish by theuse of but one valve or damper, in connection with passages andopenings, arranged to control at the same time the currents, whicheifect the double purpose of heating the oven and the water-reservoir,as described hereafter, and shown in the accompanyin g drawings, inwhich- Figure 1 is a plan view, partly in section, of a cookiugstovewith my improvements; Fig. 2, a longitudinal section on the line l 2,Fig. 1; Fig. 3, a transverse section on the line 3 4, Fig. 2; and Figs.4 and 5, perspective views, part of the outer casing being removed.

The body A of the stove is, in the present instance, of the usualrectangular form, having an oven, B, a lire-place, C, at the front, andextended at the rear to form a casing, D, with an opening, w, at thetop, for the reception of a detachable water-reservoir, F. The back t ofthe stove is out away opposite the casing D, and the space at the rearof the oven is divided by partitions c c into diving-fines b b and acentral ascending ue, d, the diving-nues com! municating with the usualsideflueswx, and the ascending flue with the central rlue y beneath theoven. rlhe bottomfof the casing D, adjacent to the back plate a, isinclined downward, forming a channel or passage, e, for a purposedescribed hereafter; and between thepartitions c c', from the pointwhere the inclined bottom j' joins the back plate, extends a iiange, g,in-

clined inward, its upper edge being adjacent to the lower edge of avalve, h, tting closely, but so as to swing freely between thepartitions c c', and Operated by a rod, a, resting in recesses in saidpartitions, projecting through the side plate of the stove, and providedwith a'suitable handle at its outer end. The upper end of the valve h iscurved, so that when the edge of the valve is in contact with theadjacent side of the reservoir E there will be a space, z, between thevalve and the reservoir, and each partition c c is cut away to formrecesses or passages t t, allowing a free communication between thespace a and the side tlues b b. The reservoir E is somewhat less indepth than the casing D, and'is contracted toward its lower end, so thatthere is a space between the casing and the sides, back, and bottom ofthe reservoir. rIhe front side ofthe latter, however, is nearlyvertical, so as to be in contact with the edges of the partitions c c,the reservoir thus closing and forming the rear sides of the lues b bfor a part of their length.

When it is desired that the products of combustion from the fire-placeshall circulate round the oven the valve h is brought to the positionshown in Fig. 2, with its edge in contact with the reservoir. The gaseswill then pass over the oven, through the diving-fines b b and bottomnues a: a, and back through the central 'iiue y and ascending fined tothe exit-opening t.

In passing through the tlues b b d the heated gases are brought intodirect contact with the inner side of the reservoir, the contents ofwhich are thereby heated.

Vhen a direct draft is required the valve It is turned to the positionshown in Figs. l, 4, and 5, and in dotted lines, Fig. 2, when the gaseswill descend the diving-nues to the recesses t' t' in the partitions cc. Through recesses they will pass into the ascending flue d, and up thelatter to the exit-pipe; but in this instance, as before, there is adirect contact of the gases with the whole inner side of the reservoir,which therefore is as thoroughly heated by the direct as by thecirculating draft around the O'ven, while the change from one to theother is effected through a single adjustment of an ordinary valve ordamper.

It will be seen that, whatever may be the position ofthe valve, there isa free circulation of the gases between the reservoir and its casing D,through the space a and the channel e, which circulation, in addition tothe direct contact of the gases in passing through the lines, stillfurther heats the reservoir and its contents. When it is desired toreplace or repair the valve or damper, easy access may be had thereto bysimply removing the Water-reservoir E.

I do not desire to confine myself to the precse construction andarrangement ot' parts described, as alterations may be necessary ordesirable in adapting the invention to stoves or ranges of di Ierentforms-such, for instance, as dispensing with one of the diving-lines, oraltering the form and position of the valve.

1 claim as my inventionl. The combination of the body A and casing D ofa stove, the partitions c c', having recesses i, the valve l1., coveringsaid recesses, and water-reservoir E, smaller than the interior of thecasing, whereby a gas-circulating space is formed completely round andbeneath the reservoir, substantiallby as and for the purpose set forth.

2. The combination, in a reservoir-stove, of a reservoir, E, partitionsseparating the diving and rising fines, and having recesses i, throughwhich said ues may communicate,

and a valve or damper arranged in one of the fines, and closing the samewhen adjusted to one position, and covering the recesses i when adjustedto another position7 all substantially as set forth.

3. The combination of the reservoir E, diving and rising hues,communicating passages t' t', and valve h, arranged to bear with itsupper edge against the reservoir and form a circulating passage, z, asset forth.

4. The combination of the reservoir-lines t d, valve h, and channel c,forming a communication in the stove, between theouter ues and aroundthe central flue, as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of mvo subscribing Witnesses.
